PigSPARQL

Pig Latin is a high-level language developed at Yahoo! Research designed for data analysis tasks, which is automatically transformed into MapReduce jobs and executed in a Hadoop cluster.
PigSPARQL is a translation from SPARQL 1.0 to Pig Latin, which allows to execute SPARQL queries on large RDF graphs with MapReduce.

  • Apache Hadoop, we recommend Cloudera's Distribution of Hadoop CDH4, the implementation is tested with CDH 4.3
  • Apache Pig, we recommend the version shipped with CDH4
  • Java Version 6
  • RDF data in (extended) NTriples format. Beyond the syntax of N-Triples it also supports the most commonly used Prefixes as well as the Prefixes used in the SP2Bench, LUBM and BSBM benchmarks.
